An Improved Clustering Algorithm for Wireless Sensor Networks

For wireless sensor networks with limited energy issues, based on the classic LEACH routing algorithm, an improved clustering algorithm of LEACH-C was presented. According to the monitoring application of limited area under the special environment, the remaining energy of the first cluster node will be introduced as a parameter of the calculation of threshold, so that the remaining energy and high energy consumption will be chosen as the first node cluster in priority, extended the survival time of the network effectively. By the simulation results show that compared with the LEACH protocol, the algorithm has good load balancing performance, thereby extending the life of the network.
